Einstein and car batteries 爱因斯坦和汽车电池 A spark of genius 天才的灵光 Without the magic of relativity, a car s startermotor would not turn 要不是相对论的魔力，汽车的发动马达就转不起来 ALBERT EINSTEIN never learned to drive. 阿尔伯特.爱因斯坦从没去学开车。 He thought it too complicated and in any case he preferred walking. What he did notknowindeed, what no one knew until nowis that most cars would not work without theintervention of one of his most famous discoveries, the special theory of relativity. 他觉得开车太复杂，再者，他更喜欢走路。而他不知道的也是直到现在人们才知道的是没有他的伟大发现之一，即狭义相对论，大多数汽车不可能发动起来。 Special relativity deals with physical extremes. 狭义相对论同物理极限相关。 It governs the behaviour of subatomic particles zipping around powerful accelerators atclose to the speed of light and its equations foresaw the conversion of mass into energy innuclear bombs. 该理论掌握了亚原子粒子在强大的加速器的作用下可以达到接近光速的速度这一表现行为。相对论的公式也预见了核弹中质能转换的现象。 |
